SFP transceiver module BlueOptics SFP-BXU34-40KM-IB-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-IB-BO is a single‑fiber SFP transceiver module designed for long‑distance optical links with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal casing with a compact SFP form factor and weighing approximately 20 g, it is intended for integration into network switches, routers and optical line equipment where a reliable fiber connection is required. The module specification includes an MTBF of 1,000,000 hours, reflecting its suitability for continuous operation in professional network environments.

Advantages

The module’s metal housing provides mechanical robustness and improved heat dissipation for stable performance. Its SFP interface supports hot‑swapping, enabling installation or replacement without powering down the host device. With support for a 1250 Mbit/s data rate and a design targeting long‑distance transmission, the transceiver balances throughput and reach for point‑to‑point fiber links. The compact, standardized form factor ensures broad compatibility with networking equipment that accepts SFP modules.

Suitable for

• Long‑distance single‑fiber point‑to‑point optical links
• Integration into enterprise and carrier network switches and routers
• Fiber backbone extensions and metropolitan area networks (where supported)
• Environments requiring hot‑swappable optical modules for maintenance flexibility

Key specifications

• Interface: SFP form factor
• Maximum data transfer rate: 1250 Mbit/s
• Housing: metal casing, silver colour
• Weight: approximately 0.02 kg
• Reliability: MTBF of 1,000,000 hours
• Optical link type: single‑fiber long‑distance transmission (module-specific)

How to use

Insert the transceiver into a compatible SFP slot on the host device until it latches, observing standard ESD precautions. Connect the appropriate single‑fiber optical cable and ensure the transmit and receive directions match between endpoints. The SFP interface supports hot‑swapping; however, follow your equipment vendor’s guidelines for online insertion and removal to avoid transient link issues. Configure the host port settings as needed to enable the 1250 Mbit/s link and verify link status through the device management interface or LEDs.

Usage recommendations

Use with compatible SFP‑capable network equipment and single‑fiber cabling rated for the intended link distance. Maintain clean connector end faces and store unused transceivers with protective dust caps to preserve optical performance. Refer to your network equipment documentation for supported transceiver types and link configuration steps.
